Feud Alert: The Kids from 'It' are Having it Out with a YouTube Makeup Artist

This might be the oddest feud of all time: One of the stars of the box office hit "It" is currently feuding with James Charles, a popular YouTube makeup artist who has had his fair share of controversies.

"Ok five minutes in and IT is already awful stay tuned for updated," Charles wrote in a now-deleted tweet. "This movie is so predictable I've been texting @beechloren02 what I think is gonna happen next & i've been right every single time so far."

After he deleted his tweets, Charles took to Twitter to explain why he didn't like "It," BuzzFeed points out.

But Finn Wolfhard, the star of the new Stephen King adaptation and "Stranger Things," wasn't having it.

"Why are you on your phone in the movie theater? Rule 1," the 14-year-old actor asked Charles.

The makeup guru initially had fun with Wolfhard's comments and walked back his initial critical tweets of "It."

Fast forward to this week for phase 2 of the feud. Charles shared a video where he gave a makeup tutorial on how to look like a glam version of "It" monster, Pennywise the Clown. In the clip's intro, Charles says he knows haters will say it is "hypocritical" and "ironic" of him to do this makeup video because of the "It" drama.

And of course, that was exactly the case. This time, Wyatt Oleff, who plays Stanley in the new "It" movie, weighed in and tweeted:
